Python Won't Run Spatial Autocorrelation Script Twice

AndrewStauffer1 — Tue, 09 Oct 2012 17:38:19 GMT

Hello,

I'm trying to calculate a Global Moran's I statistic on a [long] list of point files using python. I have set up my code to loop through the arcpy.SpatialAutocorrelation_stats script as shown below. The loop runs through the first shapefile without a problem and prints out the Moran's I Summary Table. When it gets to the second shapefile, it crashes with a strange error.

I can manually run the Spatial Autocorrelation Script in batch form without a problem from ArcCatalog. However, I don't want to parse through the Results window later.

I am using ArcGIS 10.1 with Python XY (Spyder) 2.7 on a Windows 7 64-bit machine.

Has anyone encountered this error or found any solutions?

Thanks,
Andy

import arcpy

elevationPoints = ["id_1pt.shp","id_11pt.shp"]
dataPath = r"C:\Users\Andy\Desktop\BlackbirdKnob_WV\tempPts"
for i in range(len(elevationPoints)):
    arcpy.SpatialAutocorrelation_stats (dataPath+"\\"+elevationPoints, "GRID_CODE", "NO_REPORT" , "FIXED_DISTANCE_BAND", "EUCLIDEAN_DISTANCE" ,"NONE","15")

This is the error message that comes up:

Found a temporary fix. Since it seems that the the first few errors were being derived from the MoransI.py module within the SpatialAutocorrelation_stat tool, it was re-loaded in the script with hopes that it would resolve the problem. It worked, but is still a bit of an odd work-around. See the below code that allowed the Spatial Autocorrelation tool to be iteratively executed:

import arcpy
arcpy.env.overwriteOutput
dataPath = r"c:\data"
elevationPoints = ["elevPts1.shp", "elevPts2.shp"]
for i in range(len(elevationPoints)):
    import MoransI
    arcpy.SpatialAutocorrelation_stats (dataPath+"\\"+elevationPoints, "GRID_CODE", "#" , "FIXED_DISTANCE_BAND", "EUCLIDEAN_DISTANCE" ,"NONE","15")

i already looked the same error in the internet but nobody tried to answer this question (from other people)..

i hope someone could help me...-.- please
